No-Girl

Martha Johansson, aka No-Girl, was a young telepathic mutant who ran from home after discovering her powers, only to be captured by the U-Man. John Sublime extracted her brain from her body, placed her inside a life support tank, and used drugs to force her to use her powers for his own misdeeds before she was rescued by the X-Men. Martha was then enrolled into the Xavier Institute and eventually trained as an X-Men.
